Results: Before & After
Biologically based Integrated Pest Management combines ecologically sound strategies
with other tools to provide better control and more flexibility than can be achieved using
any single tool alone. It is by far the best approach. But in the end, the most important
question is does it work. Absolutely! Just take a look at these before and after pictures
taken from different types of ecosystems. These are good examples of the kind of results
you can achieve.

|Decades of control efforts with herbicides proved fruitless
on this island, but Aphthona lacertosa took out a solid stand of spurge in just
three years. Note how quickly grasses returned. The island, which features a grassland
prairie ecosystem with relatively high moisture, remains relatively spurge-free to date.
Of interest: This site was one of the first A. lacertosa sites in the U.S.

|Mixtures of Aphthona czwalinae/lacertosa were
released here in 1994-96; their impact on heavy leafy spurge infestations between
1998-2000 were dramatic. Nearly 8 million flea beetles were collected at the site in 1999
and 2000. Refuge officials say the dramatic results have attracted a great deal of
interest from local farmers and ranchers, who are now working to implement biocontrol
programs on their own land.
